WIRE-CLOTH FOR THE MANUFACTURE OF PAPER, sto.

SPECIFICATION forming partof Letters Patent No. 284,273, 'dated September 4, 1883.

` 4Application filed July 28, 1883. (No model.)

To all whom it may concer/'11,:

Be it known that I, GEORGEE. CALDWELL, a citizen of the United States, residing at Troy, in` thecounty of Rensselaer and State of New ,York, have invented certain new and useful others skilled in the art to Which it apper tains to make and use the same, `reference being had to the accompanying drawings, and to letters of reference markedthereon, Which form Y a part of thisspecication.

This invention relates more especially to that Y p saving of fine stock is effected.

The invention consists in thearrangement and combination of parts, substantially as will fabric.

In carrying out my inventionI form an endless belt, B, of wire fabric,`and arrange the Vsame on table-rolls A of a paper-machine, the

I wires being preferably of brass or of metal capable of withstanding the decomposing effect of the pulp. l

Heretofore wire cloth or fabric arranged in the manner above Istated had the Wires arranged approximately equidistant apart, both in the -Warp and woof, so-that the openingsbe` `tweenthe wires were approximately square.

In my improved construction I` arrange the wires as shown, a a. being wires arranged close together, with `a small opening, d, between, forming in one sense a double Wire, as they shall, for convenience, be hereinafter dea'single wire, b, having wider spaces c laterally adjacent: Said Wires a a b preferably form the Warp of the fabric and take `the longitudinal strain of the belt.

In manufacturing the fabric each strand of the double wire lies in a separate heddle; but as they approach the reed they come together,

and in that manner pass through. a single a single wire, b, the Wider spaces or Openings lying on each side of the single Wire, as shwn.

2. Afabric composed of brass Woof and Warp strands, the Warp-strands a a lying closely adjacent, with the woofstrands passing alternately above and below the san1eand the strands b lying at agreater distance from either ofthe strands a b than the latter are from one another.

In testimony that I claim the foregoing I have hereunto set my hand this 24th `day of July, 1883. a
